I was in my driveway watching my young son and a few of the other neighborhood kids playing kickball in the street. One of the children pointed to the sky and asked me what those lights were. I looked up and saw what appeared to be two helicopter spotlights hovering / hanging motionless at slightly different altitudes in the eastern sky well above the tree line on the horizon. The light on the left was higher than the one on the right and there wasn't any noise coming from them. It became apparent to me shortly thereafter that these "things" were not helicopters. As I observed them, the light on the left began to dim and I noticed a shallow beam of light emenating from it. The faint beam of light broadened and narrowed as it swept slowly from left to right. This went on for maybe 10 seconds as the light to the right began to do the same thing. The dimming light on the left (towards the north) began to close in on itself slowly, sort of like the shutter on a camera, wrapping itself in a shroud of fog as it vanished. The second light, within seconds thereafter, did the same thing. Neither object moved up or down or side to side during this event. They simply vanished in the same position they were in initially. The entire event lasted approximately 3 to 5 minutes.
